"Handshake" matching MCP servers:

Enables AI agents to list, retrieve, add, and audit credentials from an encrypted vault during an active human-unlocked session, while providing no tool to unlock the vault itself.

Serves a stateless Streamable-HTTP endpoint with an echo tool, letting users observe exactly how many HTTP requests are involved in a single MCP tool call.

A learning-oriented MCP server that exposes basic tools (echo, add, reverse) over stdio transport to validate MCP handshake and tool calls.

A remote MCP server that gives MCP clients authenticated access to GitHub: repos, issues, pull requests, file contents, and search, over a proper OAuth 2.1 handshake. Runs on Cloudflare Workers.

Enables multiple MCP clients to securely access various third-party MCP backends through a single HTTP gateway, with modern MCP handshake compatibility and session lifecycle management.

Enables LLM agents to interact directly with Qualcomm EDL devices over USB, including device enumeration, Sahara protocol handshake, SoC identity queries, Firehose programmer upload, command-mode execution, and device reset.

A beginner-friendly MCP-inspired JSON-RPC server built with Node.js, offering basic client-server interaction through an 'initialize' capabilities handshake and an 'echo' function.

Enables local tool calling over Model Context Protocol via stdio, providing deterministic tools such as calc.add, text.word_count, and text.summarize_naive after JSON-RPC handshake and discovery.

Wraps a legacy MCP stdio server and presents it as a modern stateless 2026-07-28 protocol server, translating the legacy handshake and server-initiated requests.
